HAT-BRIM EDGING, SETTING, AND ROUNDING MACHINE.

Specification of Letters Patent.

Patented May 10, 1910.

AppIication filed April 7, 1909. Serial No. 488,375.

To all whom it may concern:

Be it known that I, CHARLES E. SACKETT, a citizen of the United States, residing at the city of Danbury, in the county of Fairfield and State of Connecticut, have invented a new and useful Improvement in Hat- Brim Edging, Setting, and Rounding Machines, of which the following is a specification.

This invention relates to a machine for edging, setting, and rounding, hat brims after they have been matriced or pressed into their final lateral and longitudinal curves. The machine is capable in itself of matricing and shaping the curl or reversed edge of a soft hat brim from the fiat state, but as applied to stiff hats, it is impossible to perform that process on a single machine. The edge of the hat brim must be broken down, or reversed by a preliminary process. The machine herein described is designed to supplement that preliminary process, and is especially applicable to the manufacture of stifi hats.

On October 30th, 1908, I filed serial application No. 460,353, for a hat brim curling machine That machine was very similar to the one herein described, but it was made primarily applicable to curling or reversing the edges of hat brims in a flat state, therefore applicable to the manufacture of soft hats only, and its rounding mechanism was not adapted to trimming the edge of a matriced hat brim.

On February 8th, 1909, I filed serial application No. 476,816, for a process for shaping and setting hat brims. That process described the use of a preliminary machine for steaming, breaking down, and shaping a vertical flange around the hat brim, and then finishing the curl or reversec edge on a separate machine.

On March 29th, 1909, I filed serial application No. 486,520 for a hat brim matricing and fianging machine. That machine was designed to perform the preliminary work for the machine herein described, which takes up the work on the hat brim where that machine left off. To avoid reheating or lie-steaming the hat brim to be operated upon, a quick transfer of the hat from one machine to the other is required, and the machines are designed to be placed close together, and operated as one machine;

[the process being a continuous one from start to finish. To accomplish this, both machines are fitted with upper and lower brim matrices, and positioning hat blocks exactly alike, but there the similarity ends, the functions of the machines being very different.

The matricing and curling machine herein described is illustrated on the accompanying six sheets of drawings, in which Figure 1, is a front elevation; Fig. 2, is a cross-section on an enlarged scale through the center of the machine laterally, showing a flanged hat brim in position to have a reversed or curled edge formed upon it; Fig. 3, is the same cross-section, the hat brim having been pushed down on the bed matrix, and a series of formative fingers closed over it; Fig. 4, is the same crosssection, an upper finishing matrix having descended upon the hat brim; this view shows the rounding mechanism ready to trim the reversed edge; Fig. 5, is a cross-section of the same features as shown in Fig. 4, but on a central longitudinal line; Fig. 6, is a detail view of the tongue and groove junction of the matrices, with an enlarged view of the reversed hat brim edge and trimming knife; Fig. 7, is a plan view of the rounding mechanism; Fi 8, is a cross-section through line A of Fig. F, in both figures two rounding jack arms are shown to illustrate the different positions they must assume in following the matriced curves of a hat brim, one in section, and one in elevation; Fig. 9, is a detail elevation of the arch supporting the core matrix and its connections; Fig. 10, is a longitudinal crosssection of the same on line B; Fig. 11, is a front view of the separated core matrix and inclosed finished hat; Fig. 12, is a side view of the same; Fig. 13, a plan view of the matrix, the arch in section, and the matrix removed from the hat; Fig. 14, is a plan view of the machine platform on line C, of Fig. 2, showing the adjustable bed plate, bed matrix, conformate fingers, and toe ring; Fig. 15, is a detail of the adjusting screws; Fig. 16, is a half length sectional view of the main shaft, crank, and lever bearings, all concentric with each other.

In all the views similar numerals relate to like parts.

1. Is a suitable machine frame; 2. A platform supported by it; 3. An adjustable bed plate centered over the platform (see Figs. 14 and 15), and made adjustable to and from it, by means of the corner screws 4, secured to the platform, the revolving sockets 5, adjusting nut 6, and lock nut 7 the bed plate has formed in it (see Figs. 2 to 5.), a semicircular elliptical recess 8, to receive the rounded ends of a series of movable conformate fingers 9, the fingers have a toe 10, at their base; a ring 11, secured to the bed plate projects over this toe, and prevents the fingers rising out of the recess; the fingers .have an inwardly projecting point 12, adapted to turn in and press down the peripheral edge of a hat brim, and they may be made of different heights and circumferential widths or shapes to accommodate them to the curvatures of a matriced hat brim; at the back of the fingers are projections 13, adapted to retain a close coiled circular spring 1%, which exerts a strong compressive force against the said fingers,

and makes them automatically and individually elastic in their radial movement; arranged centrally upon the adjustable bed plate within the finger circle is a bed matrix 15; it is secured to the bed plate by dowel pins and screws, common to various other bed matrices which are interchangeable with it; its upper surface is of a concave section adapted to form the lateral and longitudinal curvatures of a finished hat brim; it has a central opening 16, adapted to receive a hat block 17, which may be secured either to the bed plate, or to a flange within the matrix; its outer periphery above the face of its concavity is formed into a ledge 18 (see Fig. 6.), which acts as a tongue to enter a corresponding groove in a corresponding upper matrix, causing them to register accurately with each other; this ledge also defines the peripheral edge of the hat brim.

Arranged centrally above the bed matrix, is a core matrix 19; it has a central opening 20, adapted to receive the crown of a hat; its lower face is convex, and it is curved laterally and longitudinally to register with the face curvature of the bed matrix on which it is adapted to exert pressure, and is therefore termed a core platen; its upper face is adapted to shape the reversed peripheral edge of a matriced hat brim which is folded down upon it by the conformatory fingers; in the views shown, the reversed edge 21 is flat (Fig. 6, shows a full sized detail in section) though curved peripherally. The core platen is detachably secured to an arched member 22, (see Fig. 5, and detail Figs. 9 to 13). It is made in two halves which are parted on the inclined line 23, (see Fig. 11,) so that the halves may be slipped out from under the reversed hat brim edge; when in position, it is secured in the arch by the pins 24, and recess 25, which receives the lip 26, of the spring catch 27;

the arched member is centrally secured to a guide rod 28, (see Fig. 1), which projects upward through the center of the machine, and is secured in a cross-head 29. Rising from the platform on each side of the adjustable bed plate, are guide posts 30, which are connected at their upper end by a cross bar 31, to which they are made fast by nuts the core platen guide rod is continued upward above the cross-head to a box 33, in the crossbar to steady its vertical movement; the cross-head is provided with boxes 3%, sliding upon the vertical guide posts; proj ecting from the boxes are arms 35, in which journal pins 36 are secured. Journaled on the pins are side bars 37, which pass clownward and are journaled at their lower ends uponsimilar pins 38, secured to the extremities of cranks 39, which have their fulcrum ends keyed to a shaft 40.

Arranged upon the machine above the bed matrix, and below the core platen cross-head is a ring frame 41 (see Figs. 1 to 3), it is joined at each side to boxes 42, which have a vertical movement upon the guide posts as high as the stop collars as; the ring frame is constructed with a vertical wall 1%, and a horizontal bottom flange 45; outside of the boxes are hubs as, in which are screwed journal pins 47. Journaled on the pins are side bars 4-8, which pass downward and are journaled at their lower ends upon similar pins 49, secured to the extremities of cranks 50, which in Fig. 1 are shown projecting forward horizontally, and are keyed at their fulcrum ends to a hollow shaft 51, which surrounds the shaft 40, as shown in enlarged half-length sectional Fig. 16. The hollow shaft is journaled in boxes 52, attached to the machine frame, and is retained in position by the collars 53; outside of the machine frame on one side, is secured a lever 54, and on the other side, an arm 55, projecting horizontally rearward and carrying a balance weight 56; the lever will give a vertical movement to the ring frame on the guide posts, to and from the bed matrix.

Secured to one extremity of the interior shaft 10 is the lever 57, and at its other extremity an arm 58, carrying a balance weight 59; the cranks 39, attached to this interior shaft, abut against the ends of the hollow shaft, and act as stop collars to retain the interior shaft in position. The lever 57 on the end of the interior shaft, will give a vertical movement to the cross-head carrying the core platen on the guide posts to and from the bed matrix. It will be noted that all the levers, cranks, and balancing arms, have a common center of motion, and at times one lever will operate both shafts and all their connections.

Attached to the flange of the ring frame on its lower side by a corresponding flange 60, (see Figs. 2 to 5), is an upper matrix 61;

it has a central opening adapted to permit the arch of the core platen and the crown of a hat to pass up through it; its inner circumference 62, is the exact shape of the inside edge of the reversed welt 21, (see Figs. 6, 9 and 11), and forms the tem'plet guide by which that edge is trimmed; its bottom face 63 is curved to correspond with the edge curvatures of the core platen, and the bed matrix, on which it descends and exerts pressure; a short distance up from its curved bottom face it is recessed to form a shelf or track 64, which is exactly parallel with the bottom face curvatures; that face is also provided with a groove 65, which registers with the tongue 18, on the bed matrix, (as shown in detail Fig. 6), the outer vertical face of the upper matrix is elliptical, of the same peripheral form as the bed matrix, but of somewhat larger diameter, in order to provide a rounded bottom edge section shown at 66, in F 6, which descending upon the curved faces of the elastically controlled conformate fingers expands them as shown in F igs-t and 5, relieving them from holding down the reversed welt edge of the hat brim, and taking their place with the extreme pressure of a toggle joint'actuated by the lever 5%, and a bed conformation adapted to shape the desired finished welt or curl upon the edge of the hat brim.

Surrounding the upper matrix, is a heat ing pipe 67, perforated with burner holes to allow a mixed gas and air flame under pres sure, to play upon the matrix to heat it to such a degree as will change the nature of the reversed welt edge, (as a piece of felt,) by drying up all the solvents of the gum shellac by which it is stiffened, and change it to a structure of hardened gum having no elasticity, but designed to render the curvatures of the welt edge permanent; when covered by the hat binding, the welt edge assumes the general appearance of the ordinary stiff hat brin the elliptical heating pipe is flexibly connected by the tube 68, with gas and air supply, and rises and falls with the ring frame to which it is attached.

The rounding mechanism though shown in completed detail in sectional Figs. a and 5, is best shown in plan, section, and elevation, in Figs. 7 and 8; it consists (see plan view 7,) in a circular ring plate 69, mounted upon the flange, and revolving within the wall of the ring frame I1; it is held down by the brackets and rollers 70, secured to the wall of the ring frame; it is revolved by an upright handle 71; between it and the ring frame, is inserted an anti-friction plate 72, supplied with steel ball bearings, as shown in sectional Figs. l, 5 and 8. Mounted upon the revolving ring plate is a post 73, on which is swiveled an arm 7 l, supplied at its other extremity with a vertical hollow box 75, rising from it. The post is surrounded by a coiled spring 76, retained in position by the nut 77; one end of the spring is secured in the arm, the other end around a post 78; made fast to the revolving plate, (see Figs. 7 and 8) located in the hollow box at the end of the arm is a vertical knife shaft 7 9, which passes down inside the upper matrix; it is provided at its lower extremity with, a squared knife head 80, which bears against the vertical teinplet face 62 of the matrix, and rests upon the horizontal shelf or track (it, supported by a wheel 81, (see Fig. 8). The knife head partially split vertically to receive the knife blade 82, which is clamped in position by the screw 83; between the square shoulder of the knife head, and the lower side of the carrying arm, is a spiral spring 8st, surrounding the knife shaft, which shaft plays freely through the vertical guide box, and is topped by the retaining nut 85. it will thus be seen that the knife head and knife have a horizontal hearing pressure adapting them to bear against the vertical face of the matrix acting as a templet guide, and to follow its lateral curvatures when revolved; also that they have a verti al bearing pressure upon the horizontal track of the matrix and will follow its vertical curvatures; the knife head rolling upon the track, and the knife point trimming the edge of the welt, leaving it finished as in Figs. 6. 9 and 11.

The operation of the machine is as follows: The cross-head and ring frame being raised to their highest point on the guide posts by the two operating levers, a matriced hat with a vertically flanged brim soft and hot from a preliminary process is dropped over the hat block rising above the bed matrix; its brim then rests upon the curved head of the conformate fingers as shown in Fig. 2. Lever 57 is now drawn forward, the core platen drops within the vertical flange of the hat brim, which it accurately fits, and pushes it downward into the cavity of the bed matrix, which is a duplicate of its matriced shape, as shown in Fig. 3. In descending, the core platen expands the conformate fingers, which automatically close over it, folding the softened hat brim flange down upon it, lever 54, is now drawn forward, bringing the hot upper matrix down upon the reversed welt, its groove fitting over the tongue of the bed matrix, as shown in Fig. at. The whole hat brim is now confined within a positive mold, the greatest pressure of both toggle joints is now brought to bear upon the formative matrices in conjunction, and the levers which are arranged to hold the pressure are left until the hot upper matrix has setand dried all the solvent materials out of the welt edge, which hardens on cooling into a solid substance without elasticity. The whole process takes but a few moments, rapidity of A in movement being essential. The rounding mechanism is now revolved, and the welt ec ge trimmed while it is confined between the matrices, and the edge is rigid. In descending, the conformate fingers are again expanded by the upper matrix to make room for its foot pressure, and they are held expanded until the operation is completed; the levers are then thrown backward, the upper and core matrices rising together until above the fingers, when the matrices are separated, the hat coming away with the core matrix, as shown in Figs. 9 to 11, by pressure upon the arch spring, the halved matrices are then removed from under the welt edge, which quickly cools and harde-ns.

Various changes in constructive detail may be made, without departing from the principles of my invention, or in the process, as for instance, the rounding mechanism here shown may be dispensed with, and a pair of ring shears substituted for trimming the welt edge, as described and claimed by me in serial application, No. 450,043, filed Aug. Qtth, 1908, hat brim curling machine.
